Benefits of technology

[0015]This makes it possible to use a source of hydrogen a priori incompatible with the specifications of the fuel cells in a filling station by using a purification system of standard or non-standard technology that is fully integr

Problems solved by technology

The known and relatively inexpensive industrial manufacturing processes do not make it possible to ensure such a degree of purity continuously.
In order to guarantee a degree of purity of the hydrogen, it may be necessary t

Embodiment Construction

[0037]The filling station 100 represented by way of nonlimiting example is a station provided in order to carry out the filling of tanks 8 of gaseous hydrogen at high pressure (for example at a pressure between 300 and 850 bar).

[0038]Conventionally, the filling station 100 comprises several buffer containers 1, 2 (two in this nonlimiting example but there may be one, three or more than three thereof).

[0039]Each buffer container 1, 2, is a tank or set of tanks provided in order to contain gaseous hydrogen pressurized to a given pressure, for example respectively 450 bar and 850 bar. The station 100 comprises a fluid circuit 11, 12, 18, 4, 6 comprising a plurality of pipes and valves. The circuit is connected to the buffer containers 1, 2. The circuit comprises a first end 4 intended to be connected to at least one source 14 of gaseous hydrogen in order to enable the filling of the buffer containers 1, 2 with gas originating from the source 14.

[0040]The source 14 of hydrogen may conve...

Abstract

Method for filling a tank with pressurized hydrogen via a filling station comprising at least one buffer container and a fluid circuit connected to said at least one buffer container, the circuit of the filling station comprising a first end connected to at least one source of hydrogen gas, the circuit comprising a second end fitted with a transfer pipe intended to be connected removably to the tank that is to be filled, the method involving a step of cooling the hydrogen supplied to the tank by transferring negative calories between a cold source and the hydrogen, the method being characterized in that it comprises a step of purifying the hydrogen supplied by the source in a purification member before transferring it to the at least one buffer container, and in that it comprises a step of transferring negative calories from said cold source to the hydrogen before and/or during the purification step.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a §371 of International PCT Application PCT / FR2014 / 051264, filed May 28, 2014, which claims §119(a) foreign priority to French patent application FR1356618, filed Jul. 5, 2013.BACKGROUND[0002]1. Field of the Invention[0003]The present invention relates to a method and station for filling a gas tank.[0004]The invention relates more particularly to a method of filling a tank with pressurized hydrogen via a filling station comprising at least one buffer container and a fluid circuit connected to said at least one buffer container, the circuit of the filling station comprising a first end connected to at least one source of gaseous hydrogen for carrying out the filling of the at least one buffer container with gas originating from the source, the circuit comprising a second end equipped with a transfer pipe intended to be removably connected to the tank to be filled with hydrogen originating from the at least one buffer co...
